CHECK-TILL Specification of Letters Patent.

Patented April 2, 1907.

Application filed June 29, 1906. Serial No. 324,093-

To all whom t may concern.-

Be it known that l, CARL BLANKENAGEL, a subject of the German Emperor, and a resident of Bielefeld, Germany, have invented certain new and useful improvements in Check-Tills, of which the following is a specification.

Check-tills are already known in which a ring divided into fan-shaped compartments is arranged in such a Way that the money goes into a compartment of this ring and the ring then rotates further under a sheet of glass until at last the sum of money which has been thrown in falls through an opening in the bottom over which the divided ring itself rotates. The provision of check-tills of such a kind with a writing-strip is likewise known, said strip being moved under a glass plate, only one opening in said glass plate being left free, rendering possible the entry of memoranda. These tills broke down sometimes, however, because all movable parts were connected behind one another-- that is to say, because in moving the drivinghandle the ring divided into fan-shaped compartments was first set in motion, said ring having then to drive the writing device.

The object of the present invention consists in insuring as far as possible the simultaneous working of the separate parts by means of a special arrangement of the whole. The several movable parts are in this case so connected that the driving device simultaneously and independently sets the ring divided into fan-shaped compartments and the remaining parts in motion.

A check-till in accordance with the present invention is illustrated in the accompanying drawings, in which- Figure 1 is a plan of the closed till seen from above. Fig. 2 is a plan of the till after removal of the cover, the parts of the mechanism on the part of the lid which is able to be turned up being also illustrated however. Fig. 3 is a longitudinal elevation in section. Fig. 4 is a longitudinal elevation in section with an altered position of the handle. Figs. 5, 6, 7, and 8 are plans of the ring divided into fan-shaped compartments together with the devices for operating the same in different positions. Figs. 9 and 10 are elevations from the front and rear, respectively, of the ring divided into fan-shaped compartments.

The apparatus is worked as usual by a crank-handle 1, `which. is shown in its position of rest in Figs. 1 and 2. A two-armed lever 3 is fastened to the other end of the crank-axle 2, which is likewise shown in its position of rest in Figs. 2 and 3. Vhen the handle is rotated, which rotation takes place counter clockwise, on the one hand, the connecting-rod 5, pivoted at 4 on the front end of the lever 3, is hereby moved forward, moving the ring divided into fan-shaped compartments. On the other hand, the opposite end of the lever 3, or a pin 6, arranged thereon, slides on the lower limb of a twoarmed bell-crank lever 7 8 and presses this down. The other end of this lever carries a pawl 10, pressed upward by a spring 9, engaging the toothed Wheel 11, moving, in known manner, the strip of paper over both the rollers 12 and 13.

in Fig. 4 the position of the most important parts of the described arrangement is shown after a quarter-revolution of the crank-handle. If the handle is rotated farther, the lever-arm 7, pressed upward by the spring 14, rises again, the end 6 of the lever 3 moving backward and coming to rest again after half a revolution of the hanche. By turning the handle farther the upper end 15 of a two-armed lever 16 17 is pressed downward shortly before the pin 4 reaches its position of rest, apart from moving the ring divided into fan-shaped compartments, to be further referred to later. The other end of this lever 16 17 is hereby lifted up, it being otherwise held pressed down by the spring 1S. The hook 19 then releases the drawer 20 21, and the spring 22, which is arranged at the rear end of said drawer, pushes the drawer slightly open.

After, say, money has been taken out the drawer is pushed back again, the lever 16 17 catching again.

Now as far as the arrangement of the ring divided into fan-shaped compartments is concerned this is rotated by the connectingrod 5, as already stated. This engages, on the IOO one hand, by means of pin 4 with the lever 3 and, on the other hand, at 23 with the bellcrank lever 24 25. This bell-crank lever 24 25 is movable, on the one hand, round the aXle of the ring divided into fan-shaped compartments and carries, on the other hand, a pin 26 at its free end, to which the pawl 27 is fastened, said pawl being pressed by a spring 28 against the ring divided into fan-shaped compartments, and, further, said bell-crank lever 24 25 has a stud 29, so arranged that an intervening space remains between it and the IIO ring divided into fan-shaped compartmei'its. Further, at the rear side of the ring divided into fau-shaped coinpartnients, exactly opposite vthe money-slot 50, a pin 31 is arranged, on which a two-armed lever 33 is movable. rl`he arm 33 of this lever on the side opposite to that on which tlie handle of the apparatus is situated is pressed. by the spring 34; against the ring divided into fan-shaped compartments and is formed as a detcnt. The other end 32 is pointed and stands slightly ofi from the ring divided into fan-shaped compartments when. the arm 132:3 is pressed downI but only so far, however, that the stud 29 on the pawl 27 can catch over it.

The ring divided into fan-shaped compartments carries on its outside a circular collar 35, so arranged Ythat the pawl 27 can engage in notches in this collar, and the lever S32 in being pressed can go close against the actual ring divided into fan-shaped compartments below the collar 35.

rlhe number of notches in the collar 35 depends on the number of con'ipartments, of which seven are shown here, The ring divided into fan-shaped compartments is revoluble on the plate 36, said plate being fastened in the apparatus by n'ieans of projections at both sides. The plate 36 is cut at 37, through. which opening or sector the money which. is put into the till passes. The movement of the ring divided into fan-shaped compartments takes place in the following manner: ln the position of rest, Fig. 5, the pawl 27 engages in the notch of the collar, which is immediately behind the opening 37. The bell-crank lever 24 25 is in the position of being pulled back as far as possible. The lever 32 33 holds fast the ring divided into fanshapedcompartments. N ow when the handle is turned the pawl. 27 is in the ihrst place moved forward, and accordingly lifted out of the notch in the collar 35. After a quarter of a revolution of the handle the position of the mechanism is as shown in Fig. 6. rlurning the handle farther the position shown in Fig. 7 is attained, (after half a revolution of the handle.) The pawl 27 snaps into the. second notch in the collar behind. the opening 37. The stud 2?) is hereby pressed against the lever 32, the other end 33 of said lever releasing on its part the collar New on rotating the handle farther the connecting-rod 5 is moved backward7 and the pawl 27 thereby takes the ring divided. into fan-shaped compartments with it, the catch on the leverarm 33 slipping on the collar This movement of the ring divided into fan-shaped compartments lasts until the detent 33 comes to the next notch in the collar Then the hook 33 snaps in again and holds fast the ring divided into fan-shaped compartments. Hereupon the handle has again come into its position of rest. The position of the ring divided into fan-shaped compartments, in which the pawl 27 has just snapped in, is illustrated in Fig. 7, while F S shows the position into which the ring divided into fan-shaped compartments is talien by the returning pawl 27, whereupon everything returns to the position shown in Fig.

Figs. 9 and l() correspond to the position shown in Fig.

Now the manner of working the apparatus is as follows: In the first place the payment to be made is put through the opening 3%() and the corresponding amount noted on the paper at 3S, running over the rollers 12 and 13. The paper is in part covered by a glass plate 3Q, which renders possible a view ol' the entry last registered. The handle 1 being again rotated. the lever 7 is pressed down, and Yhe paper is in the lirst place so Yfar displaced that the writing under the glass plate 27), and thus cannot be altered. At the same time the parts of the apparatus connected with the ring divided into Vfan-shaped compariments are moved. out of the position shown in Fig. into that shown in Fig. (j. 0n lurning the handle farther a position of the apparatus according to Fig. 7 is obtained, whereupon, corresponding to Fig. S, the further rotation of the ring divided into fan-shaped. compartments takes place by an amount of one division, and thus the money-slot 30 comes into connection with a new compartment of the ring. The hook 1) is simultaneously lifted up on account of the rotation of the bell-crank lever 16, and the drawer is opened by the spring 22, the bell sounding simultaneously. After the handle has arrived again at its position of rest by pushing the drawer in again everything is prepared for the reception of Vfurther payments. Every payment remains visible Vfor more complete control until it arrives after a com plete rotation of the ring divided into fan-shaped compartments through the opening 37 to the inside of the apparatus. A metal funnel il() here serves for regulating the fall of the money.

That l claim as my invention, and desire to secure by Letters Patent, is-

1. A check-till of the type described, comprising in combination in a box, a ring provided With teeth on its outer periphery and divided into fan-shaped compartments for the reception of money revolubly mounted in said` box, a plate having an opening innnediately under said ring, a plurality of rollers mounted in said box, and adapted to hold a strip of paper, a drawer at the bottom of and normally in said box, mechanism adapted to rotate said rollers, mechanism adapted to en.- gage said drawer, mechanism consisting o'l a connecting-rod engaging a bell-crank lever revolubly mounted at the center of rotation of the ring and carrying a pawl adapted to engage the teeth on the ring in the backward movement of the connecting-rod, means IOO adapted to engage with said mechanism, a handle outside said box engaging with said means whereby on rotating the handle after money has been put into said ring the paper is moved forward, the drawer is released and the ring is rotated so that the' money falls into the drawer from that compartment of the ring over the opening in said plate, substantially as described.

2. yA check-till of the type described comprising in combination in a box, a ring provided with teeth on its outer periphery and divided into fan-shaped compartments for the reception of money revolubly mounted in said box, a plate having an opening immediately under said ring, a two-arm lever revolubly mounted on said plate one arm of same being formed as a detent and adapted to engage said teeth on said ring, a plurality of rollers mounted in said box and adapted to receive a strip of paper, a drawer at the bottom of and normally in said box, mechanism adapted to rotate said rollers, mechanism adapted to engage said drawer, mechanism consisting of a connectingrod engaging a bell-crank lever revolubly mounted at the center of rotation of the ring and carrying a pawl carrying a stud, said pawl being adapted to engage the teeth on the ring in the backward movement of the connecting-rod and said stud being adapted to engage the free arm of said two-arm lever normally engaging the teeth of the ring whereby same is released in the forward movement of said connecting-rod, means adapted to engage with said mechanism, a handle outside the said box engaging with said means whereby on rotating the handle after money has beenput into said ring the paper is moved forward, the drawer is released and the ring is rotated so that the money falls into the drawer from that compartment of the ring over the opening in said plate, substantially as described.
